Hi there! The project keeps making very good progress (only 7 blocker bugs left at the time of writing these words, some of which have fixes in review). This mean WebRender has a good chance of making it in Firefox 67 stable. I expect bugs and crash reports to spike as WebRender reaches a larger user population, which will keep us busy for a short while, and once things settle we’ll be able to go back to something we have been postponing for a while: polishing, adding new features and preparing WebRender for new platforms. Exciting!
I’d like to showcase a few projects that use WebRender in a future WebRender newsletter. If you maintain or know about one, please let us know in the comments section of this post.
